IMPROVEMENT IN LAWN OR GARDEN SPRINKLERS.

Specication forming part of Letters Patent No. 214,778, dated April 29, 1879; application filed March 24, 1879.

. represented in the accompanying drawings,

of which- Figure l is a side elevation, and Fig.2 a

vertical section, of a sprinkler of my improved kind.

My invention consists in the combination of a rotary jet-pipe and its valve and screw with .a chambered screw-coupler, its educt, and the rotary rose thereof, all being substantially as described and represented.

In such drawings, A denotes the chambered coupler, which is provided not only with a stem, a, for insertion in the ground, but with a female screw, b, to connect the coupler with a hydraulic hose. Projecting up from the coupler is an educt or tube, B, which constitutes a journal for a rose, C, to 'revolve on, there being openings leadinglaterally out of the educt and into the chamber of the rose. The rose, shaped as shown and chambercd, has one orinore openings leading obliquely out of it, and it may also be provided with A others leading vertically out of it, the oblique head or upper part the educt B is provided with a female screw, d, to receive a corresponding male screw, e, formed on a jet-tube, D.

The said jet-tube extends down through the educt, and is provided withv a valve, f, at its lower end to fit the seat c at the lower part of or below the educt. The jet-tube, where within the educt B, has a diameter less than that of the bore of. the educt, in order that when the valve is oif its sea-t and water under pressure is driven into or within the coupler, such water shall not only escape into and through the. rose, and thereby cause it to revolve on Vthe principle of the well known Barkers Mill,7 but also at the same time be driven up through andout of the jet-pipe, so as to produce a jet decm.

On revolving the jet-pipe so as to bring the valve up to its seat, the water will be cut oft from the rose,-and will escapeby the jet-pipe
